Trading History Balance

I need to access trading history balance for 2 Classes of magic numbers and be filtered using:

• recent time (hours) // Input variable;
• limit history (number of trades in history)  //Input variable

Class 1

T History balance (Last 72 hours  //make it an Input variable, and Last 20 trades  //make it an Input variable, ) for magic numbers  1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 including open and closed positions to reflect current balance (sum of profit/losses for those magic numbers made in the last 20 trades)

Class 2

T History balance (Last 72 hours  //make it an Input variable, and Last 20 trades  //make it an Input variable, ) for magic numbers  101, 102, 103, 104,105, 106, 107, 108, 109, 110, 111, and 112 including open and closed positions to reflect current balance (sum of profit/losses for those magic numbers made in the last 20 trades)

Then Code

//Global declaration

bool _Compare_1;

bool _Compare_2;

int start() {

  
   //Local declaration
  _Compare_1 = (Class_1 > Class_2);        // To trigger _Conditional_Arithmetic
  _Compare_2 = (Class_1 Class_2)
{
   if(Condition) Value1 +=Value2;
   return(Value1);
}


double _Conditional_Arithmetic_2(bool Condition, double Value1, double Value2)     // To be triggered by _Compare_2 = (Class_1 < Class_2
{
   if(Condition) Value1 +=Value2;
   return(Value1);
}

//Then I will merge this code with my EA. Does it make sense?
